Other authors are noted in the change history that follows (in reverse chronological order): 1999-11-04 lpd Edited comments slightly for automatic TOC extraction. 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5); added conditionalization for C++ compilation from Martin Purschke <purschke@bnl.gov>. 1999-05-03 lpd Original version. */#ifndef md5_INCLUDED# define md5_INCLUDED/* * This code has some adaptations for the Ghostscript environment, but it * will compile and run correctly in any environment with 8-bit chars and * 32-bit ints.
